Webcam intégrée non détectée sur un Alienware M17x R3 pour Ubuntu 20.04

J'ai un Alienware M17x R3. J'ai récemment installé Ubuntu 20.04 et je sais que la webcam fonctionnait auparavant. J'ai appuyé sur FN + F9 Cette touche est affichée comme une touche caméra mais la caméra n'est détectée dans aucune application (fromage, zoom, etc.).

J'ai tapé lsusb :

J'ai tapé dmesg :

Je vois d'ici dmesg il est indiqué que l'on appuie sur la touche FN + F9 J'ai essayé d'activer la caméra ET qu'elle est USB (semble-t-il) même si elle est "intégrée". Mais rien ne se passe. Comme vous pouvez le voir sur dmesg il est indiqué que l'USB est déconnecté pour le dispositif.

Je ne peux pas l'allumer via le BIOS.

Qu'est-ce que je fais de travers ?
